2.系统技术特点
2.1自动离合系统
营口临潼维宁系列风力发电机有机械自动离合系统，摆脱了传统风机启动风力要求高的束缚，使得在很小的风力条件下就可以启动风机，大大提高了风机发电效率。
2.2自主偏航电磁减速
营口临潼维宁风机带有自主偏航系统，在风力不大的情况下可以主动将迎风面对准风向，以得到最大的迎风面积，提高风机的工作效率；在风力过大的时候，自主偏航将风机迎风面调离最大迎风面，电磁减速系统则输出电磁阻力，使风机减速。避免因转速过高导致的“飞车”情况，保护了风机。
2.3风光互补的优势
风机在任何有风的时候均可实现发电功能，弥补了太阳能在阴雨和夜间不能发电的优势，真正实现了电力的互补。
1. Basic principles
Wind-PV hybrid power-supply system generally includes wind turbine, solar battery components, intelligent management core, inverter, dissipative load, battery and support, etc. The detailed working principles to see figure 1.

2. Technical features
2.1 Automatic clutch system
Yingkou Lintong Weining wind turbine has mechanical automatic clutch system, so it’s free from the tie which traditional wind turbine will start under the condition of large wind power. The wind turbine will start under the condition of small wind power, which greatly improves the generating efficiency of the wind turbine.
2.2 Automatic off-course and electromagnetic deceleration
Yingkou Lintong Weining wind turbine have automatic off-course system, it’ll actively face the wind direction to get the largest windward area to increase the efficiency of the wind turbine. When the wind power is too large, it’ll automatically adjust the windward of the wind turbine to be away from the largest windward and the electromagnetic deceleration system will output electromagnetic resistance to slow down the speed of the wind turbine, which avoid the situation of "off-fan" caused by excessiverotational speedand protect the wind turbine.
2.3 Wind-PV hybrid advantages
The wind turbine can realize the function of power generation at any time as long as the wind blows. It compensates the disadvantage which solar energy can't be used to generate electricity in the rainy days and nights and really realizes electricity compensation.
